  • Patent number: 7576167
    Abstract: Disclosed is a moisture-curing type curable resin composition containing: a curable resin intramolecularly having a silicon-containing functional group; and a Lewis acid or a complex of the Lewis acid as a curing catalyst, the Lewis acid being selected from the group consisting of metal halides and boron halides, which is rapidly cured at room temperature. The silicon-containing functional group is represented by general formula: —SiX1X2X3 or —SiR1X1X2 (wherein, X1, X2 and X3 respectively represent a hydrolytic group and may be the same as or different from each other, and R1 represents a substituted or unsubstituted organic group having 1 to 20 carbons). If the silicon-containing functional group is —SiR1X1X2, the curable resin further contains intramolecularly a polar component that is one of urethane, thiourethane, urea, thiourea, substituted urea, substituted thiourea, amide, and sulfide bonds, and hydroxyl, secondary amino and tertiary amino groups.

  • Patent number: 7251171
    Abstract: A register part of a mode register has a plurality of operation setting parts in which plural types of operating specifications are respectively set to operate the semiconductor memory. The mode register outputs a soft reset signal when at least a value of one-bit of the register part represents a reset state. A reset signal generator outputs a reset signal for resetting an internal circuit in response to the soft reset signal. In the present invention, a system that controls the semiconductor memory is required to necessarily assign a predetermined bit with a setting command of the mode register in order to generate the soft reset signal. Accordingly, it is possible to reliably reset the internal circuit by external control.

  • Patent number: 6907555
    Abstract: The present invention is a self-test circuit (BIST) incorporated in the memory device, which is activated in response to a test activation signal from outside. When this self-test circuit is activated in response to a test activation signal (WBIZ) from outside, it generates a test operation command (WBI-CMD), generates a test address (WBI-ADD), and generates test data (WBI-DATA). Furthermore, after the self-test circuit writes the test data to a memory cell, it effects a comparison to establish whether or not the read data that is read from this memory cell is the same as the test data that was written thereto and stores information as to the result of this comparison. This comparison result information is then output to the outside.

  • Patent number: 6681996
    Abstract: The configuration of this passport printer reduces the burden of reentering adjusting and setting values of passbook printers. When a control card 3 is replaced by another card, the adjusting and setting values of a passbook printer 1 stored in a nonvolatile memory attached in the control card 3 are written in a separately prepared magnetic stripe by using a magnetic head 41. Then, after the replacement of the control card 3, the adjusting and setting values written in the magnetic stripe are read by using the magnetic head 41, and stored in the nonvolatile memory of a control card 3 as a new replacement.
